Average light spread = 1100-1200 PPFD

The new High Light 420 “Longboard” comes fully assembled, ready to grow. Each fixture replaces 600-750W of HPS/CMH with the most efficient “true” full spectrum light on the market.

Fixtures can be hung individually or in multiples to cover larger areas. Two Longboards can be hung side-by-side in a 1.2m x 1.2m or 1.5m x 1.5m tent to outperform any “bar light” LED, providing more wattage, a better spectrum, and complete coverage with the ability to hang at different heights for staggered canopies (see attached PAR maps).

Designed and manufactured by Grow Lights Australia and LED Teknik, these quality fixtures have enhanced UVA and Far Red light that have been proven in grow rooms and greenhouses around the world to boost essential oils and yields.

These are one of the best LED grow lights on the market. The combination of UVA and Far Red light produces outstanding quality with faster fruiting and flowering times.

These Longboards feature the latest High Light 420 “Gen2” LED panels with higher levels of UVA, Violet and Far Red light.

There is no need for supplementary UV or Far Red lighting – which reduces complexity and cost compared to other LED grow lights – as High Lights provide a complete spectrum on one channel (one driver) with more even coverage due to the evenly spaced diodes.

Each High Light is built with (real) top-bin Japanese Nichia mid-power and UV diodes, and custom LED Teknik 660nm, 730nm and narrow-band phosphor technology paired to genuine Mean Well drivers. Industry-leading efficiency of up to 3 umol/j is the result of high-quality componentry, Australian innovation and years of hands-on research and development.

Quality materials include Italian-made quick-release Techno Connectors and chemical-resistant German LAPP cable with an attractive slim-line profile – all designed and assembled in Australia. The HLG series drivers are mounted remotely to reduce heat, but can be mounted to the heatsinks if required.

All High Light 420 grow lights now ship with fully water-resistant LEDs.


High Lights are powered by genuine Mean Well HLG series drivers with seven-year warranties. The drivers are mounted remotely on a 4.5m water-proof cable to reduce heat build-up in the LED panels and grow room (heat reduces LED efficiency).

HLG-320H-48A (370W) – this driver punches well above its weight and delivers 340-350W to the LEDs and pulls around 370W from the wall. These drivers have onboard dimming and are best suited to rectangular grow areas of up to 1.2m 0.6m, or in pairs up to 1.2m x 1.2m (or slightly bigger).

HLG-480H-54A (500W) – this driver represents good value and delivers up to 470W to the LEDs and pulls around 500W from the wall. These drivers also have onboard dimming and are suited to rectangular areas of up to 1.5m x 0.8m, or in pairs up to 1.5m x 1.5m (or slightly bigger).

High Light 420 “Longboard” fixtures can be ordered with Mean Well AB type drivers that have a separate dimmer wire that can be linked to a remote dimmer, central controller or light harvester for full automation. However, for general growing we recommend the cheaper, simpler and waterproof A type drivers that are set up at the Grow Lights Australia factory to delivery full power at all times. These drivers can be dimmed using onboard dimming dials, however most growers tend to “set and forget” once they have their grows dialled in.
